5 oi Ohio, have invented certain new and useful Improvements in Lifting-Jacks, of

'which the following is a speciiication.

The invention relates to lifting jacks of the'character usually employed for raising le the axles of automobiles' and other like vehicles; and the object o the improvement iste provide a lifting jack of comparatively small height and extensibility, which canA be used under the different axles of the same vehicle which are locatedat different heights irom the supporting surface.

The general object of the invention is attained by providing a rest on the upper end of the rack of the jack 'for raising the higher axle, and extending downward therefrom external to the base, to a con nection with the lower endo'f the rack, a bracket upon which .is provided another rest for raising the lower axle of the vehicle.

A further object of the improvement is to provide means for adjusting the supplemental rest so that the same may be placed in different positions on' the bracket without removing and returning any screws, bolts or other `fastening means The several objects of the invention,thus set forth Ain general terms, are attained by the construction and arrangement illustrated in the accompanying drawing forining partr hereof, in which,

Figure 1 is a. side elevation of the improved rack; Fig. 2, a vertical section of the same; and Fig. 3,.a perspective View of he supplemental rest.

Similar numerals refer to similar part-s th rr iughout the drawings.

The base l of the jack is provided with the vertical guide-wav 2, in which is lo-.

cated and operated the rack il, which is raisd and. lowered by the usual mechanism shown collectively at l by means of :i handle, the socket 5 of which is provided. with a suitable extension, not shown. One side ot' the base is provided with the vertical slot (i. the edge flanges of which form a suitable bearing or guide for the abutting side o'lt the rack extending to the bottom of' the hase; and the upper end of the rack is provided with the rest 7, which is used ilor Jraising axles and other objects nor- Spec'caton of Letters Patent.

mally.A located above the upper end of the l y base of the jack.

.T he bracket 8 is formed or secured on one side of the rest 7 andextends directly downward outside the corresponding wall 9 of the base of the jack, to a point opposite the lower end of the rack; and upon the lower end of the bracket is provided the l0 which .extends through the slot 6 in the wall 9 of the jack and is secured to or connected with the lower end of the rack. rest l1 is provided on the bracket 8 for use in lifting axles or other objects normallylocated below the upper end of the base; and as shown this rest is adjustable upward and downward On the bracket 8,

ybut suchl adjustment of the supplemental rest is not essentialto the improvement in For a ready adjustment of the supplementalarest 1l, its inner end is provided with the bail or loop 12 adapted to engage around the bracket 8, and upon its lower side is provided the dependlnt detent 13 which is curved inward and adapted to engage in one of the sockets 14 formed by the series ofteethor lugs 15 on the outer side of the bracket 8. By this construction and arrangement `it is evident that the bracket 8 which carries the supplemental rest is secured not only at its upper end but4 at its lower end with the rack 3, and that it 'has no contact or dependence whatever upon vthe base l, excepting only that the lateral bar 10 extends through the slot -t and acts as a .stop forr'the rack at bottom of the base in one side wall thereof,f

a rack located andV operable in the guide way and bearing on 'the edge ilangesfof the slot, va rest on'tlie upper end of the rack,l

a bracket extending downward from the rest external to the base and having a lateral bar on its lower end extending through cev The supplemental the slot and connected Awith the lower end
